Australian 20yo medical student stabbed to death in car

A 20-year-old Australian university student promised her friend she would get home safe after a night of partying, but hours later was found stabbed to death in her car next to her critically-injured father.

Sabrina Lekaj died outside her family home in Adelaide's Kidman Park on Sunday night after partying with her friend in the CBD. Her body was found beside her father, Petrit Lekaj, in her Mercedes Benz. Her father had sustained severe stab wounds to his abdomen. 

"Her last words were, 'I love you and I'll message you when I get home', and that's all I heard from her," Lekaj's friend, Kat Valstar, told 7News.

It is understood police will allege her father, 49-year-old Petrit Lekaj, stabbed her before turning the knife on himself.

He was dragged from the vehicle and remains sedated at the Royal Adelaide Hospital under police guard and on Tuesday was charged with murder, 7News reports.

A bedside hearing with the Port Adelaide magistrates court is scheduled for Friday.

Police started searching for the vehicle shortly before 10:30pm on Sunday after the family expressed "concern for the occupants", Daily Mail reports.

The 20-year-old has been described as highly intelligent and outgoing, studying medical imaging and classical piano performance at the University of South Australia. She graduated high school with an ATAR score (Australian Tertiary Admission Rank) of 99.35.

A number of friends have posted tributes to Lekaj on social media.

"I can't believe I'm writing this. My beautiful Sabrina. Incredibly talented pianist, high achiever and queen of dark humour. I love you," one friend posted to Instagram.

"I'm in shock, upset and trying to comprehend what's happened," Valstar told 7News.

"Everyone's having breakdowns and I'm trying to, you know, push through the fact that she's gone."
